3 Claims. (CI. 33-50) The invention concerns a telescopic sight mounting for guns. It concerns more particularly a telescopic sight mounting comprising a relatively fixed portion which is attached to the gun and a removable portion which carries the sight and is pivotally and removably connected to the fixed portion whereby the removable portion of the mounting may be swung to one side, or alternatively, may be removed entirely from the gun.

It is an object of the invention to provide a telescopic sight mounting of the type described in which the removable portion of the mounting may be removed from the gun quickly, possibly within one second or less.

Another object of the invention is to provide improved means for pivotally and removably connecting the removable portion of the mounting to the fixed portion.

A still further object of the invention is to provide improved latching means for use in retaining the removable portion of the mounting, which carries the sight, in its operative position.

The invention will be readily understood by referring to the following description and the accompanying drawing, in which:

Fig. l is an elevational view, partly in section, of a te1escopic sight mounting embodying the invention, as applied to a gun.

Fig. 2 is an elevational view taken on the line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 2, showing the telescopic sight swung to one side.

Fig. 4 is a plan view taken on the line 44 of Fig. 1.

Fig. 5 is an elevational view, partly in section, of a modified form of the invention.

Referring to Figs. 1 to 4 of the drawing, in Fig. l a portion of a gun is shown, the gun having a stock 1, a barrel 2 and a cartridge chamber 3, the cartridge chamber 3 being disposed rearwardly of the barrel 2, in the usual manner. A telescopic sight, shown in dotted lines, is designated by the numeral 4. The telescopic sight 4 is pivotally and removably connected to the gun by the telescopic sight mounting of the invention, as hereinafter described.

The telescopic sight mounting of the invention comprises an elongated, upstanding bracket 5, which is disposed parallel to the cartridge chamber 3 and wholly on one side thereof. The bracket 5 is attached to the cartridge chamber 3 by a plurality of screws 6, and one side of the bracket 5 is curved at 7 to correspond to the curvature of the cartridge chamber 3. A tubular member 8, which likewise is disposed parallel to the cartridge chamber 3, is carried by the upstanding bracket 5 and is rigidly connected to the upper edge thereof.

A fixed pin 9, one end of which is rounded at to form a ball joint, is inserted in one end of the tubular member 8 with the rounded end 10 extending outwardly therefrom. A movable pin 11, one end of which is rounded at 12 to form a ball joint, is inserted in the opposite end of the tubular member 8 with the rounded end 12 extending outwardly therefrom when the pin 11 is in its outer- "ice 2 most position. A compression spring 13 is disposed within the tubular member 8, between the fixed pin 9 and the movable pin 11, whereby the movable pin 11 is urged outwardly with respect to the tubular member 8.

A cam 14, which is connected to one end of a lever 15, is disposed partly within the tubular member 8 and partly within a connecting slot 16 formed in the upper edge of the bracket 5. The cam 14 engages a notch 17 formed in the under side of the movable pin 11. The lever is pivotally connected to the bracket 5 at 18, so that the movable pin 11 is moved to the right, as shown in Fig. 1, upon depressing the lever 15. Upon releasing the lever 15 the movable pin 11 is returned to its original position by the action of the spring 13.

The portion of the telescopic sight mounting above described, all of which is carried by the bracket 5, is relatively fixed, being attached to the cartridge chamber 3 by the screws 6. The mounting also includes a removable portion as hereinafter described, which carries the sight 4 and is pivotally and removably connected to the fixed portion by ball joints which are formed in part by the rounded ends 10 and 12 of the pins 9 and 11.

The removable portion of the mounting comprises a pair of end members, numbered 19 and 20, which are rigidly connected to each other by a rod 21, and each of which has a ball socket 22 therein for engagement by the rounded ends 10 and 12 of the pins 9 and 11. Each of the end members 19 and includes a circular band 23, formed integrally therewith, which is split on one side, at 24, and is adapted to be clamped about the sight 4. The portions of the band 23 adjacent the split 24 are clamped together by a screw 25.

The removable portion of the mounting may be readily swung about the ball joints formed by the ball sockets 22 and by the rounded ends 10 and 12 of the pins 9 and 11, from the position shown in Fig. 2 to the position shown in Fig. 3. Alternatively, the removable portion of the mounting may be quickly disengaged from the fixed portion by merely depressing the lever 15 whereby the movable pin 11 is disengaged from the corresponding socket 22.

In the construction above described, the spring 13 is capable of applying the correct pressure to the ball joints comprising the rounded ends 10 and 12 of the pins 9 and 11, and the corresponding sockets 22, which preferably are hardened and lapped, to consistently return the sight to the same setting regardless of the number of times the sight is removed. The structure is so rigid that a force suflicient to physically damage it would be required to alter the alignment of the sight and its mounting. Use of the spring 13 eliminates the human element involved in judging varying degrees of tightness, as when a nut or screw is used, but at the same time a determined pressure on the lever 15 is required to remove the sight from the gun.

The telescopic sight mounting of the invention further includes means as hereinafter described for latching the removable portion thereof in the position shown in Fig. 2. One of the end members, designated by the numeral 20, has a ing 26 having a ball socket 27 therein for engagement by a pin 28, one end of which is rounded at 29 to form a ball joint. The pin 28 is partially enclosed within a cylindrical housing 30, which also encloses a compression spring 31 which urges the pin 28 outwardly for engagement with the socket 27. The housing is mounted on a small plate 32, which is attached to the gun by a plurality of screws 33. A knob 34 is connected to the pin 28 and extends outwardly thru a slot 35 formed in the housing 30 whereby the latch may be disengaged by moving the pin 28 to the right as shown in Fig. 4.

Referring to Fig. 5 of the drawing, a modified form of the invention is shown in which latching means as hereinafter described is provided whereby the removable portion of the mount may be yieldably retained in the position shown in Fig. 5, or alternatively, the position indicated by the dotted lines, and in which the removable portion of the mounting may be readily swung from one of such positions to the other upon disengaging the latching means, which is accomplished by merely applying sufficient force to overcome the pressure exerted by the latching means.

In the embodiment of the invention shown in Fig. 5, the removable portion of the telescopic sight mounting comprises a pair of end members 36, which correspond to the end members 19 and 20 shown in Figs. 1 to 4. The end members 36 are rigidly connected to each other by a rod 37, which corresponds to the rod 21 shown in Figs. 1 to 4, and each of the end members 36 has a ball socket (not shown) corresponding to the sockets 22 shown in Figs. 1 to 4, for engagement by the rounded ends 10 and 12 of the pins 9 and 11.

Each of the end members 36 includes a circular band 38 which corresponds to the circular band 23 of Figs. 1 to 4, and is slotted on one side, at 39, adjacent the band 38. The band 38 is adapted tobe clamped about the sight 4, and may be tightened with respect thereto by manipulation of a screw, shown in dotted lines, whereby the portions of the end member 36 on opposite sides of the slot 39 are drawn closer together.

One or more transverse bores 40 are formed in the rod 37, preferably adjacent the end members 36. A small ball 41, and a compression spring 42 which acts upon the ball 41 to urge it outwardly, are disposed within each of the transverse bores 40. The ball 41 is selectively receivable in one of two ball sockets 43 which comprise depressions formed in the peripheral surface of the tubular member 8, on opposite sides thereof, whereby the removable portion of the mounting is yieldably retained in the position shown in Fig. 5, or alternatively, in the position indicated by the dotted lines.

A small knob 44 extends downwardly from one of the end members 36 for engagement with the cartridge chamber 3, whereby the removable portion of the mounting is additionally supported in the position shown in Fig. 5.

The latching means shown in Figs. 1 to 4 provides a positive latch which must be released manually before the sight may be swung outwardly from the position shown in Fig. 2. The latching means shown in Fig. 5 provides an arrangement in which the application of force alone is suflicient to swing the sight in either direction.

The invention may be modified in various ways without departing from the spirit and scope thereof.
